IDEA用Maven创建SpringCloud(Finchley)的聚合项目以及踩过的坑

一.创建父项目

• File–>New–>Project
• –>Maven–>Create from archetype–>maven-archetype-quickstart-Next
• –>GroupId={你的GroupId}–>AritifactId={你的ArtifactId}
• –>Next–>Next–>Finish–>New Whindow

二.创建子项目

• 右键点击项目名称–>New–>Module
• 选中Spring Initializr–>Next
• –>Group={主工程的GroupId}–>Aritifact={当前模块的ArtifactId}、
• –>Next–>Next–>Finish
  这样一个主项目和子项目就创建好了
  
  名称可能不同，可以删去多余的文件

三.配置Pom文件

1.父项目的pom文件

2.子项目pom文件

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0modelVersion>

四.启动子项目

• 在主启动类上加上注解 @EnableEurekaServer

@SpringBootApplication
@EnableEurekaServer
public class EurekaApplication {

    public static void main(String[] args) {
        SpringApplication.run(EurekaApplication.class, args);
    }

}

• application.yml 文件配置

	 eureka:
	   client:
	    defaultZone: localhost:8080/eureka

• 启动主配置类
  
  看到这个界面就成功啦
